Photodiode Current Formula, Example & Calculator

This calculator determines the photodiode current (I) using the formula: I = R * P Where:

• I is the photodiode current in amperes (A)
• R is the responsivity of the photodiode in amperes per watt (A/W)
• P is the optical power incident on the photodiode in watts (W)

Photodiode Current Calculator

Example Calculation: Let’s say we have a photodiode with a responsivity of R = 0.5 A/W, and it is exposed to an optical power of P = 2 mW (which is 0.002 W). We can calculate the photodiode current (I) using the above calculator with the given values for R and P.

Inputs:

• Responsivity (R): 0.5 A/W
• Optical Power (P): 2 mW (0.002 W)

Output:

• Photodiode Current (I): 1 mA

This means that the photodiode will generate a current of 1 mA when exposed to an optical power of 2 mW with a responsivity of 0.5 A/W.
